Nursing Elites

1. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.

2. A client with hyperparathyroidism is preparing for surgery. Which preoperative lab finding is most important to report?

• A. Elevated serum calcium.
• B. Decreased serum albumin.
• C. Elevated serum potassium.
• D. Elevated serum magnesium.

Correct answer: A

Rationale: The correct answer is A: Elevated serum calcium. In hyperparathyroidism, elevated calcium levels can lead to complications such as kidney stones, bone pain, and fractures. During surgery, high calcium levels can affect neuromuscular function, cardiac function, and blood clotting. Therefore, it is crucial to report elevated serum calcium levels preoperatively to prevent potential surgical complications. Choices B, C, and D are not directly associated with hyperparathyroidism and are less likely to impact the surgical outcome in this scenario.

3. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

4. The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?

• A. Frequent syncope
• B. Muscle rigidity
• C. Gait instability
• D. Fine motor tremors

Correct answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

5. Which of the following statements reflects appropriate teaching to prevent injury in a client with rheumatoid arthritis?

• A. Use heat applications to relieve swelling and stiffness.
• B. Take warm showers before activity.
• C. Use cold packs to relieve joint pain.
• D. Take prescribed anti-inflammatory medications with meals.

Correct answer: C

Rationale: The correct answer is C. Using cold packs to relieve joint pain is appropriate for clients with rheumatoid arthritis as cold therapy is more effective at reducing inflammation and pain in these conditions. Heat applications may exacerbate the symptoms by increasing swelling. Taking warm showers before activity may provide comfort but does not directly address joint pain or prevent injury. While anti-inflammatory medications are commonly prescribed, they are not directly related to preventing injury in clients with rheumatoid arthritis.
